In 2008 a massive movement will be started by individuals
who are fed up with the election process that exists in
the United States.

This is what will happen:

The citizens in this group will start mailing out envelopes
filled with small amounts of various powdered substances
normally found around the house.

These envelopes will be sent to the addresses available on
the Internet for all the candidates that the persons
are NOT in favor of.

This is why:

In 1991 an engineer, working in Boca Raton, Florida
wrote an e-book about this different form of terrorist
warfare (available Free on web site http://www.farviewu.biz).

Ten years later, just after the 9-11 event another event
occurred (see http://en.wikipedia.org/wiki/2001_anthrax_attacks).

Based on this post 9-11 their envelopes will close up the
candidates offices and possibly even the post office.
It may even shut down the 2008 election.

The individuals involved in the act will spend about
50 cents (51 cents now) for each envelope mailed out. As long as
they are careful to not leave finger prints on/in the envelopes or
stamps and use bogus return addresses they will not be traceable.
